Title:
金属接着性で疎水性の導電性コーティングを堆積させる方法
Document Type and Number:
Japanese Patent JP6943852
Kind Code:
B2
Abstract:
A process for depositing, on a substrate, at least the surface of which is at least partially metallic, a metal-adhesive, hydrophobic and electrically conductive coating based on electrically conductive microparticles and on a polymer matrix P comprising at least one thermoplastic fluoropolymer P1 and a thermosetting resin P2 comprises at least the following steps: in a first container, dissolving the polymer P1 in an organic solvent, referred to as first solvent, of this polymer; in a second container, dispersing the electrically conductive microparticles in an organic solvent of the polymer P1, referred to as second solvent, identical to or different from the first solvent; adding, in the first container, the thermosetting resin P2 in the liquid state; mixing the contents of the first and second containers, then depositing the mixture obtained in this way on the substrate; and crosslinking the resin P2 and removing the solvents, in order to obtain the targeted final coating. The process of the invention is advantageously implemented for the application of such a coating on a fuel cell bipolar plate made of steel, in particular of stainless steel.
